The family

God gave Abraham a child. A child so there would be a future Messiah on the earth.
Issac was his name. The godly family heritage will came from Issac.
God gave Issac a wife so he would have children. It is important to have children to maintain a family's name. 
Jesus is the Messiah. Jesus is God. He has always existed. He came to this earth. He lived a perfect life and died on the cross. And he resurrected from the dead.
We must repent from our sins and follow him. We are sinners. We must have a new nature so we must accept Jesus.
